As of September 30, 2010, it is reasonably possible that the amount of unrecognized income tax benefits may increase or decrease during the following twelve months.

Included in the provisions is a change in the federal income tax treatment of the Medicare Part D subsidy. For periods beginning after December 31, 2012, we will no longer be entitled to receive a federal income tax deduction for payments made to provide our retirees with prescription drug benefits which equal previous subsidies we received from the U.S. government for providing retirees with prescription drug benefits. We had previously recorded a deferred income tax asset for the tax benefit of future payments made with respect to this subsidy. As a result of the Act, we have written-off $3 million of deferred income tax assets as a component of income tax expense from continuing operations for the nine month period ended September 30, 2010. </div>  </div>   <div style="margin-left: 0%">  <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 0%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> </div> <div style="margin-top: 0pt; font-size: 1pt"> </div>  </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Description containing the entire income tax disclosure.
